Abstract The replacement of fishmeal (FM) with economical and nutritious FM alternatives including plant animal-based protein ingredients has become a global research priority. However, the presence several anti-nutritional factors (ANFs) in these may impair nutrient utilization fish. supplementation exogenous protease as feed additives could be an effective approach to improve digestibility al...

Twin-screw extrusion cooking trials were performed to investigate the differential effects of conventional DDGS (DDGS) and HP-DDG inclusion, as fishmeal replacers, on physical properties (moisture content, water activity, thermal properties, expansion ratio, unit density, bulk density, water absorption, solubility and pellet durability indices, and color) of Rainbow trout (Oncorhynchus mykiss) ...

Defatted microalgal biomass derived from biorefinery can be potential feed ingredients for carnivorous fish. The present study investigated the growth, feed intake:gain and health parameters in Atlantic salmon fed for 84 days with defatted Nannochloropsis oceania as a fishmeal replacer. Fish fed feeds containing the algal biomass (at 10 and 20% inclusion, alga groups) were compared with groups ...

The effects of storage temperature and time on raw pink salmon by-products were evaluated in relation to the fishmeal produced. Chemical analyses were performed on the raw and processed by-products at two temperatures. Total volatile base nitrogen values indicated substantial spoilage by day 2 at 15.4 ± 1.4°C and day 6 at 6.0 ± 0.8°C. For most biogenic amines in raw by-products stored at 15.4°C...
